Problems solved by technology

[0008] The existing 4G UDR virtual network function (VNF) has basically been transplanted from physical devices to virtual machines, but the basic software architecture has not been fully resolved, so it has not achieved complete separation from the infrastructure, guaranteed by network function virtualization (NFV) Optimal degree of operational automation or operational expense (OPEX) reduction

Abstract

The present invention relates to a method of obtaining the user subscription data pertaining to a subscriber in a telecommunication network. The method comprises the steps of receiving, by a coexistence function, a trigger from a network function (NF), the trigger indicating a need for user subscription data pertaining to the subscriber; determining, by the coexistence function, that the user subscription data is not available in a unified data repository of the telecommunication network; obtaining, by the coexistence function, the user subscription data from a user data repository, upon the determining that the user subscription data is not available with the unified data repository, wherein the user data repository and the unified data repository is accessible by two separate communication interfaces; and transmitting, by the coexistence function, to the NF, the obtained user subscription data. A corresponding coexistence function and a computer program product are also presented herein.

Description

technical field [0001] The present disclosure relates generally to fifth generation (5G) telecommunications networks, and more particularly to a method of obtaining user subscription data from a data repository in a 5G telecommunications network. Background technique [0002] Fifth generation (5G) telecommunication systems are being standardized by the 3rd Generation Partnership Project (3GPP). A disruptive change has been agreed, where traditional end-to-end interfaces and protocols are modified through a so-called Service Based Architecture (SBA) comprising multiple Network Functions (NFs), where, with the help of the Protocol, each NF acts as a producer to provide one or more services to one or more consumers. [0003] A user data management (UDM) function in a layered architecture such as a telecommunication network includes a UDM front end (FE) and a database. This database in the 5G Technical Specification (TS) is named Unified Data Repository (5G UDR), while in the ...
